The E4990A Impedance Analyzer has a frequency range of 20 Hz to 120 MHz. The E4990A provides an industry best 0.045% (typical) basic accuracy over a wide impedance range, with a 40 V built-in DC bias source. The equivalent circuit analysis function supports seven different multi-parameter models and helps you to simulate your own equivalent parameter values of components. Five frequency options (20 Hz to 10/20/30/50/120 MHz) and frequency upgrades allow you to choose the most appropriate option with the latest amount of investment. With the option 001, enhanced measurement speed option, the low-frequency (10M/20M/30M/50M) models of the E4990A are as fast as the flagship 120-MHz E4990A model. It’s suitable to reduce overall cost-of -test for accurate evaluation like resonators or inductors or incoming inspection where many points per device or many DUTs measurements are required. The E4990A supports a wide variety of test accessories that designed to make measurements simple and reliable. Whether you are in R&D, QA, or inspection, the E4990A is an ideal solution for characterizing and evaluating electronic components, semiconductor devices and materials. Application Example:
Passive components: Impedance measurement of capacitors, inductors, ferrite beads, resistors, transformers, or crystal/ceramic resonators.
Semiconductor components: C-V characteristics analysis of varactor diodes. Impedance evaluation of diodes, transistors, amplifiers, or MEMS.
Other components: Impedance evaluation of components on printed circuit boards.
Dielectric material: Permittivity and loss tangent evaluation of plastics, ceramics, and printed circuit boards.
Magnetic material: Permeability and loss tangent evaluation of ferrite, amorphous.
